To be a DD fighter, even though I am not sure you can call it that. Put 25 into SPR for the crit and all the rest of yuor stat points in STR. Also, carry an Axe. As far as your empowerment points go, if you are looking for damage, you may want to increase the damage in your main skills.
However, this is just what I think. I built my tank to be a tanker not a DD. Also, I am moving this to the fighter section.
Good luck with your fighter.
EDIT: lvra beat me, lol.
